I predict you will enjoy AuroMatic upmixing significantly more than DSU for 2-ch music. I know I do. :) It does not steer center content (there is a little bit of sound added center output), so the...

Hi Brandon,

Not sure how you'll be integrating the QSC EQs into the multi-subwoofer tuning. REW using the Seaton method, perhaps?

And if you're familiar with REW, I wonder if I could interest...

One of the possible reasons Alcons uses the extra 10 dB signal levels is that it makes the connections 10 dB more immune to induced noise. This might be of benefit in a commercial cinema -- a...

Easy enough to test. Move the suspect channel's XLR cable to the known good output of the Trinnov. Does it sound normal? If so, it seems the Trinnov is not outputting the same signal in both cases....

Have you checked to see if that speaker is performing like the others? Such as: Play a signal from a good speaker. Connect the suspect speaker's cable to the good amp channel. Does it sound the same?

I suspect you are hearing the power transformer. It is not uncommon, unfortunately. I have had other brand amps that did the same, and could be heard across the room (when silent). I was unable to...

In case you have not done some basic sleuthing, here's some ideas to help isolate the cause:
